Specification of Letters Patent.

Patented Nov. 13, 1906.

Applicationfiled June 8, 1906. Serial No. 320,879.

T 0 all whom it may concern:

Be it known that I, ALFRED GAsPARY, a subject of the German Emperor, residing at Markranstadt, near Leipsic, Germany, have invented certain new and useful Improvements in Apparatus for Molding Tiles, Slabs, and the Like of Plastic Material, of which the following is a specification.

This invention relates to improvements in apparatus for molding tiles, slabs, and the like of plastic material.

In the specification of my previous patent, No. 804,944, I have-described apparatus for molding profiled tiles, slabs, and the like. The present invention relates to improve ments in this apparatus which enables the latter to be used with equal facility for mold ing plain and profiled tiles and the like. The improved apparatus also comprises a smoothing-tool or strickle connected by bars to a yoke which is pivotally supported in longi tudinal guides. To allow of using-the apparatus for the manufacture of smooth tiles or the like, it is essential that the connectingbars should be located above the strickle or in the same plane as the latter, but in no case below the strickle.

In the annexed drawings, which illustrate the invention by means of examples, Figure 1 is a perspective view of the apparatus; Fig. 2, a detai View illustrating a modification; Fig. 3, a perspective view illustrating a further modification, and Figs. 4 and 5 are detail views.

p designates the smoothing-tool or strickle, which is connected by bars Z to the yoke s, the latter being mounted, by means of gudgeons 2, in lateral guides a, fixed to the molding-table.

The novelty of the construction shown in Fig. 1 as compared with that described in my previous patent cited lies in the fact that p the bars 1 are located above and not below the strickle p. The horizontal movement of the parts p, Z, and 8 produces a com ression of the surface of the plastic materia on the molding-table to form a flat plate or slab.

In the modification shown in Fig. 2 the connecting-bars Z lie in the same plane as the smoothing-tool or strickle p, being fixed to the u per surface thereof and bent at right ang es, so that they lie in the plane of said tool.

A more suitable construction, however, is shown in Fig. 3, in which the desired condition is still fulfilledviz., that the connecting-bars do not lie in a lower plane than the smoothing-tool. The novelty of this modification lies in the fact that the smoothingtool may be rotated about its length axis, for which purpose the said tool is provided with a projecting gudgeon p at eachend, rotatably supported in lugs or end bearings p on the connecting-bars Z. or strickle p can therefore execute three different movements: first, a horizontal movement in conjunction with the yoke s,'-secondly, a movement in the vertical plane about the pivots 2 of the yoke s, and, thirdly, a rotary movement about its longitudinal axis. The pins 19 also serve as handles for the operator, by which the tool may be brought into the desired position over the molding-box for the smoothing operation. This form of smoothing-tool preferably has a cross-shaped section, as shown in Fig. 4, and comprises a plurality of bars p one'of which'may be flat or smooth and the remainder provided with various profiles p With this machine having a single strickle the plastic material may be first com res'sed with the smooth surface of the stric le and then shaped or molded with any of the profiled surfaces, according to requirements. Instead of using the smooth surface of the tool the latter may be inclined and the edge thereof used for cutting off the excess mateilgial in place of rubbingoff same, as shown in What I claim as my invention, and desire to secure by Letters Patent of the United States, is

1. The combination of a molding-table, guides connected therewith, a yoke adapted to have sliding and rotary movement in said guides, bars connected to said yoke and a strickle attached to said bars, the latter being-located in a plane not below the o erative surface of said strickle substantial y as described.

2. The combination of a molding-table, guides connected therewith, a yoke adapted to have sliding and rotary movement in said guides, bars connected to said yoke and a strickle mounted on said bars and capable of rotation about its longitudinal axis, the bars aforesaid being located in a plane not below the operative surface of said strickle, substantially as described.

3. The combination of a molding-table, guides connected therewith, a yoke adapted to have sliding and rotary movement in said guides, bars connected to said yoke and a This smoothing-tool strickle having extended pivots rotatably mounted in said bars and serving as handles, the bars aforesaid being located in a plane not below the 0 erative surface of said strickle substantia y as described.

4. The combination of a molding-table, guides connected therewith, a yoke adapted to have sliding and rotary movement in said guides, bars connected to said yoke, and a strickle rotatably mounted in said bars and having a cross-shaped section, the bars aforesaid being located in a plane not below the operative surface of said strickle.

5. The combination of a molding-table, guides connected therewith, a yoke adapted to have sliding and rotary movement in said guides, bars connected to said yoke and a strickle of cross-shaped section rotatably mounted in said bars and having a smooth and variously profiled surface, the bars aforesaid being located in a plane not below 'the operative surface of said strickle, sub

stantially as described.

In witness whereof I have signed this specification in the presence of two witnesses.

ALFRED GASPABY.
